The American Academy of Periodontology and the European Federation of Periodontology held a World Workshop in 2017 to develop a new classification of periodontal disease to replace the almost 20-year old classification system (1999). The results of their efforts were unveiled in June of 2018 during the Europerio Conference held in Amsterdam, and concomitantly published in both the Journal of Periodontology2 and the Journal of Clinical Periodontology.3 Since its adoption, clinicians and educators worldwide have sought to improve understanding of the new classification system and its clinical implementation. The purpose of this course is to provide a succinct and easy to follow guide to help both clinicians and students understand and implement this new (2018) classification system of periodontal and peri-implant diseases and conditions in their practices.
